Description

Floor hinge cover of waterproofing {Floor hinge cover of superior water proofing property}

The present invention relates to a floor hinge cover with excellent water resistance, and more specifically, to prevent water from flowing into the floor hinge even when the hinge assembly having the hinge axis is changed by adjustment in a box-type case embedded in the floor of a building. It is about a cover that can do it.

In general, the floor hinge is embedded in a box-shaped case of a hinge assembly, in which a hinge shaft which is coupled to a lower side of the door from one side is protruded to an upper side, and the upper surface of the case is embedded in the bottom of the building where the door is installed. The open top of the cover is to be covered with a plate-shaped cover having a hinge shaft hole so that the hinge shaft is exposed to the top. On the other hand, when the hinge assembly is embedded in the building floor in a pre-mounted state in the case, its position can be finely adjusted in front, rear, left and right directions with respect to the case so that the hinge axis extends in the vertical direction accurately.

And the cover can be divided into integral cover and split cover. In case of integral cover, it is impossible to adjust the hinge assembly because the box type case cannot be opened unless the door is completely removed after installation of the floor hinge. The split-type cover consists of a first cover part having a small area divided by a hinge axis hole through which the hinge axis of the hinge assembly penetrates from one side of the cover, and a second cover part having a large area. Since the cover can be removed even when the door is engaged, the box-shaped case can be easily opened to facilitate the adjustment of the position of the hinge assembly. However, the hinge shaft hole must be larger than the cap size of the floor hinge assembly through which the hinge shaft penetrates in order to cope with the position adjustment of the hinge assembly. It was impossible to adjust the position of the floor hinge assembly because of the corrosion of the positioning bolt used to adjust, and there was a problem such that water flowed into the floor hinge assembly, causing the floor hinge to malfunction.

As a result of carefully examining the problems of the prior art, the inventors of the prior art, if the position of the hinge assembly is adjusted, can provide a close contact between the cover and the cap of the hinge assembly exposed through the hinge shaft hole of the cover. It was found out that the problem can be solved and came to complete the present invention.

Therefore, the object of the present invention is that even if the position of the hinge assembly is changed by the adjustment between the cover and the case, the water flows into the floor hinge through the hinge shaft hole due to the close contact between the hinge shaft hole of the cover and the cap assembly of the hinge assembly. The present invention provides a floor hinge cover having excellent waterproof properties.

The present invention aims to solve the problem of failure of the floor hinge caused by the inflow of water by maintaining the close contact between the hinge axis of the cover and the hinge assembly even if the position of the hinge assembly is changed by adjustment.

Explanation of Signs of Major Parts of Drawings

3 ... split external cover, 5 ... guide protrusion, 6 ... 1st internal cover.

9. Second internal cover.

The present invention is generally made of a first cover portion 2-1 and a second cover portion 2-2, which form the hinge shaft hole 1 when abutted with each other as illustrated in FIGS. Stainless steel outer cover 3, a hinge shaft hole 4 corresponding to the hinge shaft hole 1, and a first cover portion 2-1 and a second cover portion 2-2 The first inner cover (6) made of rubber plates with guide protrusions (5) for bringing abutting portions into contact with each other, and having a size larger than that of the hinge shaft holes (1) and (4), It consists of the 2nd inner cover 9 of rubber | gum which covers 8).

In the second cover portion 2-2 of the outer cover 3, an opening 11 for adjusting the working fluid pressure adjusting screw 10 in the hinge assembly 7 is formed. 11, a female screw 12 is formed, and the opening 11 can be opened and closed by a countersunk head screw 14 fitted with a 0 ring 13. The first inner cover 6 is made of a rubber plate having the same size as the outer cover 3.

First inner cover 6 As shown in FIGS. 3 to 7, the first cover portion 2-1 and the second cover portion 2-2 of the outer cover 3 come into contact with each other. Guide protrusions 5 for keeping the parts in close contact are formed on the surface.

The guide protrusion 5 is composed of a T-shaped guide protrusion 5a and an I-shaped guide protrusion 5b as shown in FIG. On both sides of the vertical extension portion 5c which the guide protrusions 5a and 5b have in common, an end portion and a second cover portion of the first cover portion 2-1 of the outer cover 3 respectively. The end of (2-2) is in close contact with each other, and in particular, the horizontal extension portion 5d formed on both sides of the T-shaped guide protrusion 5a is an end of the first cover portion 2-1 of the outer cover 3. Space where the end portion of the first cover portion 2-1 and the end portion of the second cover portion 2-2 can be fitted to cover the upper portion and the upper portion of the end portion of the second cover portion 2-2. To provide.

As shown in FIG. 6, the lower part of the first inner cover 6 is formed with a semicircular protrusion 15 extending to the edge, and the semi-circular protrusion 15 has a case as well shown in FIG. When assembled with the flange 17 of the 16 and the screw 18, the screw 18 and the through-holes 19 are arranged, and the annular projection 15 'formed around the hole 19 is formed. When the screw 18 is tightened to perform the role of a spring washer and also to seal around the screw 18. One side of the first inner cover 6 is provided with a check window 20 used to maintain and repair the hinge assembly 7.

As shown in FIGS. 2 and 8, the second inner cover 9 includes a circular protrusion 23 having a hole 22 formed at the center of the hinge shaft 21 of the hinge assembly 7. Concentric circular flanges 24 larger than the circular protrusions 23, and large and small concentric circular projections 25 and 25 'are formed on the flanges 24. As shown in FIG.

The present invention constructed as described above is assembled as illustrated in FIGS. 1, 2 and 8, wherein the second inner cover 9 first covers the hinge assembly 7 in the form of covering the cap 8 of the hinge assembly 7. And the first inner cover 6 is later assembled on the second inner cover 9, and the first cover portion 2-1 and the second cover portion (2) of the outer cover 3 2-2) the case together with the first inner cover (6) in a preassembled state to be in close contact with both sides of the guide protrusion (5) around the guide protrusion (5) of the first inner cover (6) It is fixed to the flange 17 of the 16 with a screw 18.

1 and 8, the second inner cover 9 and the first inner cover 6 covering the cap 8 of the hinge assembly 7 are in close contact with each other, A portion where the first cover portion 2-1 and the second cover portion 2-2 of the outer cover 3 covered on the cover 6 abuts the portion of the first inner cover 6. Since it is in close contact with the guide protrusion 15, it prevents the inflow of various foreign matters around the cap 8 of the outer cover 3 itself and the assembly of the hinge assembly 7.

According to the present invention, the outer cover 3 and the first inner cover 6 and the second inner cover 9 are always in close contact with each other even if the setting position of the hinge assembly 7 is adjusted in the case 16. Not only is maintained, but the first cover portion 2-1 and the second cover portion 2-2 of the outer cover 3 are guided by the guide protrusion 5 of the first inner cover 6. Since the state in which the close contact is maintained, the opening portions of the hinge shaft holes 1, 4 and the first cover portion 2-1 and the second cover portion 2-2 of the outer cover 3 are in contact with each other. By effectively preventing the introduction of various foreign substances, including water into the floor hinge has the advantage that can be used for a long time without fear of failure.
